I'm curious about this detail, and I have what is surely a very dumb question. Both titanium and carbon fiber are, afaik, known and used for their strength to weight ratio; so aerospace is a natural application. But in deep sea diving is weight a factor at all? Could one just build vehicles with, I don't know, a 30 cm thick steel plate?

- CydeWeys 3y agoIt's super easy to add buoyancy by attaching it to the hull outside the pressure vessel. James Cameron's design uses a metal pressure vessel with an advanced foam composite outside of it for buoyancy.
